Suspicion

Long ago, in a tiny Kingdom,
in some far-distant land,
lived four hundred sub-servient people,
whose ruler was "The Shan"!
He had a real bad temper,
and was subject to take fits!
So the people sorta walked on eggs,
and had to keep their wits.
Things were good for quite awhile,
no fits, and it was great!
Then one day, that all changed,
which led to a perilous fate!
It's unclear what really happened,
but things got real intense!
The Shan had his worse fit ever,
and the people had no defense!
There was only one survivor,
a very lucky man!
But, I have to ask, where was this guy,
when "the Fit hit the Shan?
